, To all whom it may concern Be it known that I, LAMBERT J 2' Bone, a citizen of'the United Statesof America, re siding inthe city and county of Bhfladelphia State of" Pennsylvania, have invented e certain new and useful I prqveinent in Fiexible Metallic Train-Pipe Connections, of vi hich. the fpllowin is a true and exact -clesci'iptimn reierence ei ng had to the ac conip ai ying drawings which form a part thereon v v "laym n invention relates to flexible metallic pipe connections and the ob ect of the invention is to rovide a connectionof character suita le for use as arailway train pipe connectiomand which embodiesa snap coupling part, and is of such flex bility that it can be read ly and safely usedin plae flqf endiat nhe ae ly. with he t n ieyireispipebpe w i'me j s now in er a. 11sec l of; construction and; arrangement; pointed out in the appended claims, and one embod1= n ent is fully illustrated and described n1 The invention consists in certain features the accompanying drawingsand descriptive.

matter to which reference should he had for a full understanding of the invention and e. di'ent se he f-1 Of the drawings: Figure 1 is a perspective View of t vo similar train pipe connections constructed in accordance with, my invention the twoeonnections being uncoupled he e 111i? them to be coupledtogether by the snap coupling parts attached thereto. Fig. 2 is elevation showingone of my improved train pipeconnections coupled to a train pipe hose connection of standard form. Fig iiis an end 'elevation of my improved train pipe connection as shown in Figs. 1 and 2, Fig. 4 is a section taken parallel.

to the plane oflthc pzi er withrespect to ig. 3, data portion ofrt e apparatus shown atfi ure. In the drawings, A represents the snap coupling part of-iny improved connection.

The partA is pivotally connected by a joint 1 tp the lower; end of a swinging pipesection B. The upper end of the pipe section is pirotally connected by afioin t F? to the lo terend'of an elbow pipe section C and the upper endo f the section Q'is pivotally connected by; ajoint F to thellqwer endofian nerallyvin the relative positions to per= valve E at the endoftrain pipe fi proppr in the same manner in which the ni'etallic end connection EE' of the standard hose connection is secured into the valnefE es shown. at I the right hand-of" Fig. With, this particular arrangement, the co' {p hose connection formed-oh parts A, B;J, and E,' as above described may V r usedintcn changeably with the standard hose connec hate '1)- tion, which, as shown in. Fig. 2 comprise,

snap coupling part AA, flexible hose section G- and a metallic and connection EE, The various joints, F, F F F"and"F*, may be, and'as shownare identical/in con: struction, In the form'shown, at B3Qll .i(lllltk one of-the pipe sections connected'isiorme with a socket portion F, receiving" packin -washers F -which surrounds the c vliiidrica portion F and the other pipe section conmated by the joint. The inner end of" the portion F has a bearing in the other pipe section at the inner' end of'the recess F and is grooved to receive a'packin ring F which abuts against the hott'om o the, recess F at one ond and is engaged atthe other end by the adjacent packing ring F31, The packing rings F -aro retained in place and the two pipe sectionsjoin sd together are secured against movement in the direction right angles to the axesotthej'oints F Ft The axis of the joint F418 stationary ot'courso, with respect to the train pipe ami in the preferred form iiiustratedis parallel to,tl1e longitudinal: anis of the ca; to whi h I joints VF and F respectively. Preferably coupling part A from the train pipe,--..One

that the arrangement shown, with joints F,

,cnd of the elongated swinging pipesection and transverse to the general direction of I disclosed herein,

the connection is applied. With this arrangement bf the joint F,- the. axis I of the joint F is generally speaking, vertical,and the axis 0 the joint F is, generally speaking, horizontal and transverse to the axis of the joint F though of course, these axes shift somewhat in operation as the connection adjusts itself to diiierent relative positions of the train pipe section connected thereby. The axis ofthe joint l as shown is parallel to the axis of the joint F In the particular construction shown the swinging pi c section BB is formed of a body of pipe t readedinto the ends-of elbows B and B Whichenter into and form parts of the elbows B and B and Care all arranged to act together in laterally displacing the advantage of this displacement of the coupling part is that it facilitates the coupling and uncou ling operations. The coupling part A, so ar as its couplin characteristics are concerned may be idiantical with any standard or suitable coupling partused in train pipe connections. In the 0011-. struction shown, the coupling part A co n; prises a coupling part proper which is. threaded on to one end of an elbow part A the other end of which fiormsa part of. the joint F. A train pipe connection must have a very large degree offlexibility to accommodate 1 the difi'erent relative movements of the ends of the train pipes connected together. The relative movements lgtween ends of adjacent and connected train pipes involve many components: the axes ofthe connected train pipes have angular movements'comprisin'g components in planesparallel and transverse to the general direction of the train pipes, furthermore, the connected endsof thetrain pipes have a relative movementof approach and recession with components both parallel the train pipes I have found by extended, and longv continued tests, and experiments I? and F in proximit to each other and with the axis of one o the joints at right angles to the axes of the other two and with the coupling parts jointed to the lower 13, will give the train pipe connection as a whole flexibility necessary to permit a ready coupling and uncoupling of the snap coupling parts, and to' avoid rupturing or unduly straining the joints in the use of the apparatus; have'found also that the 'necessary flexibility and ease in couplin can not be obtained vviththe same num U1 of joints except by following the arrangement lit-muse of the inherently longer life and greater SilvHLjilll and safety of the metallic connection, the desirability of using train pipe connections formed of jointed metallic pipes in lieu of the standard rubber hose connections has long been recognized, and

other fluid is conveye Itwill be apparent to those skilled in the art that some changes in the formiof the apparatus disclosed may be madewithout Having now described my invention, what I claimpasnew, and wish to secure by LettersPatent,is: r Q 1.
